` readily withdrawn from the holder to leave the syringe in condition for use.

A further object of the invention is to provide a construction ci this character which may be simply and inexpensively manufactured and which is readily applied to and removed from the needle.

These and other objects I attain by the construction shown in the accompanying drawing, wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein Figure l isa sectional view through a hypodermic needle package constructed in accordance with my invention; and

Fig. 2 is a side elevation showing one section of the container removed to enable the needle to be applied to the ampule.

Referring now more particularly to the drawing, the package comprises large and small tubes l0 and Ii, each having their outer and closed end adapted at their inner ends to engage with a stopper I2. The stopper I2 has a central recess I3 opening through one end thereof, the recess being of such depth that it leaves a relatively thin membrane I4 at the opposite end. This recess receives and closely fits the smaller tube Il, and the exterior of the stopper receives the larger tube I0. The side walls of the stopper are tapered as clearly shown, and it Will be obvious that the more force which is employed in forcing the tubes upon the stopper, the more effective the seal between the stopper and both tubes.

In use of the package, the insertion end, or that end I5 of the needle which is `applied to the patient in making an injection, is extended through the membrane I4 and into thetube Il, the enlargement I6 with which such needles are formed abutting the membrane to limit the movement of the needle therethrough and prevent damaging contact with the end of the tube I I. The friction provided by the engagement of the needle in the membrane will maintain the 'the needle and forced upon the exterior of the stopper I2. When it is desired to employthe needle, the tube IIJ is removed, as shown clearly 5 in Fig. 2, and the end I1 of the needle applied to the ampule. During this operation, the engagement of the enlargement I6 with the stopper will enable suflicient force to be exerted to drive the end il of the needle through the rubber stopper (not herein shown) with which the ampule is usually provided, following which the stopper I2 and tube I I may be readily slipped from the end I5 of the needle.

It will be obvious that a package of this type 15 may be very conveniently applied to and removed from the needle, and not only affords a means for` maintaining the needle in sterile condition but, likewise, provides a guard preventing Vdamage to the needle. When the tubes are formed of 20 transparent material, it may be very readily determined whether the package contains a needle or not and, accordingly, glass is preferably employed in the construction of tubes IIJ and I I.

Since the construction herein described is capa- 25 ble of considerable modification without in any manner departing from the spirit of my invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1.` A hypodermic needle package comprising a, pair of tubes each having its outer end closed, and a stopper engaging both of said tubes and connecting adjacent ends thereof, said stopper having a relatively thin membrane confronting 35 the bore of each tube, which membrane is readily pierceable by an end of the needle.

2. In a hypodermic needle package, a pair of tubes each having its outer end closed, and a stopper connecting said tubes, at least one of 40 the tubes being engaged in a recess in the stopper, said recess providing a relatively thin wall confronting the bores of the tubes and readily pierceable by a hypodermic needle.

V3. A hypodermic needle package comprising `a. 45 pair of tubes each having its outer end closed and having their combined length greater than the needle that they are to receive, and a stopper connecting adjacent ends of the tubes, said stopper tting into one of the tubes and having a 50 recess receiving the other of the tubes, said recess being of a depth such that it affords at the closed end of the stopper a relatively thin membrane readily pierceable by the needle.

4. A hypodermic needle package comprising a 55 pair of tubes each having its outer end closed and having their combined length greater the needle that they are to receive, and a per connecting adjacent ends 0f the tubes, s

5 stopper ttng into one of the tubes and havin recess receiving the other of the tubes, said than stopaid cess being of a depth such that it affords at the closed end 0f the stopper a relatively thin membrane readily pierceable by the needle, the side Walls of the stopper being tapered.
